After seeing some undetailed Facebook messages that he didn't like, Salvador Sanchez-Orozco and his wife, Faye, split up. But apparently they had long been having difficulties. A relative told KOMO News:

Salvy loved Faye but he didn't know how to express it. The only way he could express it was to lash out at her.

No doubt this is not a way to express your love. And apparently Faye got sick of it, for soon, she began seeing another man after their split. Nevertheless, Sanchez-Orozco continued to help take care of his 2-year-old daughter, Daveena.

But last month, things took a turn for the worst when Sanchez-Orozco apparently tried to hang himself with a dog leash. He also threatened to take his daughter to Mexico. Still, however, he was allowed to visit his little girl, as no one suspected he would end up doing the unthinkable despite his very troublesome behavior.

But then Sanchez-Orozco came to pick up his daughter one day and found a man visiting his estranged wife. He didn't do anything about it then, but came back on an unscheduled day to get his daughter. He was allowed to have her, as surely the wife had absolutely no idea what was seething inside.

Prosecutors say that the distraught dad brought Daveena to his home and then "squeezed" her until she could no longer breathe. He then tried to take his own life -- this time with a dog collar around his neck. But he called police and asked for help.

Police found him alive, but it was too late for little Daveena. He reportedly told detectives: "I strangled her, I snapped."

The little girl's great-grandfather says the only possible motive for doing this would be to "get back at Faye."

How I truly wish that parents would never get to this point. How horrible can things be that you would take your child's life in revenge? It's bad enough to deprive your child of a parent by taking your own, but snuffing out a young life that loves and trusts you ... it's just unthinkable.
